Title: Valve Clearances....
Post by: TheMasterRat on July 15, 2004, 07:35:53 PM
Ok, so I finally got my feeler gauges from kbctools ( some mishap with the delivery  :roll: )

Here's the clearances I pulled and after I will explain how I took them.

#1 Cylinder ( Left side of the bike )
 Intake - .051mm   /   Exhaust - .051mm
#2 Cylinder
 Intake - .051mm   /   Exhaust - Less than .025mm (Didn't have smaller)

I took the measurements by rotating the crank until the cam lobes pointed upwards. Then starting with the larger feeler gauge, worked my way down in size until the feeler gauge slid freely under the lobe.

Did I do this right?  :dunno:

As far as the #2 Exhaust goes, I suppose I need to pull that shim, find out what it is and replace it with the correct size using Kerry's chart, right?

As long as the lobe is on the base circle (nose pointing away from valve) then that's how I'd do It. GS500 luv,luv forum.

At those sizes, make sure that you don't have 2 blades stuck together.  2 blades are still thinner than most of the single blades in a set.

I did that to myself a while back and thought I had a tight valve. 20 min. later, it was correct. That's when I realized that I measured the first time with 2 blades.

Impossible with the set I've got. They're individual blades in a vinyl case.

You can rotate the bucket right now, and make sure it was not open all the time... but yes a slightly thinner shim... I'll pull that shim measure it, and pull a shim in my pile closest to it but thinner and put that in...
Cool.

Well, I don't have a shim pile or the motion pro tool or a micrometer. So I figure I'll order the two tools, and find out what it is and what I need, then probably get the shim from the dealer?

Yep, that's the procedure.

I guess you'll get the Motion Pro tool from Dennis Kirk, or have you found a different source?

Do you plan to get a micrometer ... or dial calipers?  (Just curious, because the dial calipers seem more generally useful to me.)  Either way, a metric unit would be great ... but they're hard to find in the U.S. of A.  I recently picked up dual display, SAE / Metric dial calipers at my local Harbor Freight.  I've been using an SAE-only Harbor Freight set for a few years now.  They work just fine, but I was getting tired of having to multiply the reading by 25.4 all the time to get millimeters.

If you're tight for bucks, you could probably get the shim you need for next to nothing from Srinath or ... who was that other guy...?   :dunno:   If you happen to need the one size I have (which I have 2 of) it's yours.  But if your local dealer has a good price, go ahead and it there -- IF they have it in stock.

QUESTION:  Are you still the proud owner of a refuses-to-pass-the-emissions-test GS500E?  It's been 3+ weeks, hasn't it?  Time to borrow Ed-in-Az's K&N air filter and leave the restrictor off.  Or somethin!!

Yea... however my shim stack is all odd sizes... I ahve a 262, a 269, a 248 etc... loovely, makes the shim chart entirely useless.  :lol:
Cool.

I got a digital metric/SAE micrometer the other week for $25 from checker (a big auto parts chain, not sure what they are called elsewhere) Considering the quality of some of their tools, I was a little nervous. So far, so good though.

If you're cheap like I am, its not a bad option.  :lol:

Unfortunately I still have an engine in many, many pieces.

Well, after the dealer F$*@ed up my parts order twice (I got a 15% discount out of the ordeal though), I finally got my parts. I have started the reassembly process, but broke off one of the crankcase bolts earlier tonight. I got it out, but I need to go get a new one. Hopefully I will finish this weekend, but I'm waiting until my engine is running before I make any plans to ride.

Yes, I still love my bike :kiss: . I'd love her more if she was running, but like I said that should be soon.

Bummer. I tried to respond to an earlier post of yours concerning whether or not you could use an automotive ring compressor. You don't really need a compressor on most bike motors. You should see a chamfer at the bottom of each cylinder. When you put the jugs on the pistons just use a wooden dowel or similar tool and push the rings into the lands as the jug goes onto the pistons. It helps if you have someone to give you a hand. (no jokes about clapping please). Ya gotta love the little GS dontcha...an' this forum too.

Yes, I'm the non-emission passing GS500.. But a few things came up ( rusty tank ) while I was checking things over and I might as well fix it up now while I have it apart.

I found the Motion Pro tool ( I think ) at Sudco.com. I plan on getting the digital dial caliper from Harbor Frieght too. Shims are yet to be determined ( only need one anyway, just have to get the tools to find out which one )

I'm going to start the POR-15 process on the tank tonight ( Marine Clean and Metal Ready tonight probably. May wait until tomorrow or Monday for the MR.. )

Can anyone tell me if that tool ( A ) works on the GS500? It lists most suzuki bikes except ours... I'm going to call and ask as well ( since they don't take online orders anyway.. )

That is the right tool.  Dennis Kirk also carries it.  (See my post in the ok then (http://www.gstwins.com/forum/viewtopic.php?t=8784) thread.)
